There's a cryptic image posted over on Eidos-Montreal's website right now which shows a big question mark along with the words "Eidos-Montreal's second project to be revealed soon." Text posted above this image confirms that the first new project currently being worked on will be a new game in the classic Deus Ex franchise, but no clues are given about the second project.

Enter the detective poster from the Through the Looking Glass forums. Going by the username jtr7, this eagle-eyed forumite concluded that the font used on the promotional image is the exact same font used in previous games in the Thief series. Win.

Posting a snapshot from one of the series which shows an in-game map, it's easy to see that Eidos-Montreal has used a very similar monochrome color scheme for the new promotional project image.

Other comments from the forumites mention that if it is indeed a new Thief game, then Eidos will likely want to reboot the franchise and offer different gameplay styles than those seen in the older games.

Lets hope "reboot" means something more like "Thief Anniversary". Recreating Thief 1 with updated graphics like they did on Tomb Raider would be far more enjoyable than what Eidos Montreal could come up with.

I've been playing Thief 2 for the first time in several years and just having a blast. I am not sure I have played any game since Thief 2 that I could say is better. I really want a proper Thief 4, but a redone Thief 1 would be ok. Just don't be the aborted Ion Storm Thief 4 which was set in a more modern setting. That would bring on the death murder kill rage.

Actually, if I recall, the way the last thief game ended setup a new thief series pretty well and tied up a lot other arcs.

Spoilers on that:

Spoiler for Hiden:

Basically, the whole watcher society collapses, everything. But, Garret finally accepts and takes his place as the father of a new watcher organization. As he's walking the streets he goes through a scene just like the beginning of Thief 1 where a talented thief girl sees him, and tries to pickpocket him. He catches her and says that quote that went along the line of he has work for her, for it is hard to spot a watcher, especially one that does not wish to be seen.

So, female protagonist in the new one, with an old Garret heading up this new watcher organization?

It seems as though Eidos is working hard to revive its famous franchises of several years past. Last year we saw confirmation of Deus Ex 3, and it looks like a convergence of information points toward a reveal of a new game next week. Joystiq points to both Eidos Montreal's Twitter feed and a new issue of Edge Magazine, which contains a teaser alongside pullquotes from GameSpot and GameSpy for what appears to be a new Thief game.
